TYPE-SETTiNG AND LIiiE-cAsriivG maciamii.

To all whom it may concern: v

Be it known that I, HEINRICH DE'GE ER, 26 Hollmannstrasse, Berlin, German Empire, manager, having invented certain new and usefulImprovements in or Relating to Type-Setting and Line-Casting Machines, dohereby declare that the following is an exact specification of the same.

This invention relates toiniprovements in matrix setting and type line casting mamat-rices are set into lines, whereupon metal castings in the shape of lines are prepared fromthe'said set matrix lines, and the castings in question are used direct for printing.

The improvements relate to the casting device. r it In the accompanying drawings Figure -1 shows the casting device, Fig. 2-shows in vertical section the ,casting pot with thepump cylinder, and Fig. 3 shows it in sectional .plan. p v d I,

This application is divided from my, application Serial No. 556.441, filed April 19, The casting device proper remains the same as in the old constructions, but a.dis'

' advantage is obviated,-which was, due, to the fact that, owing to the; oscillatiori ofthe casting pot, the pump-piston moveddownward in the cylinder, duringgits I movement forwardtoward the matrix line, andin that y m t m exp ll d l d iro s the boiler. This is avoided by the curved path of movement of the pump lever having been modified so that the pump leyer is raised to the same extent asthat to which the piston is moved relatively to, the castin'g p ot sothat the relative position fgthQp mp piston and of; the casting'pot remains un; changed... .This construction is, shown in F al- The sting po 6 isrbta ly a e ranged-in the known manner about thepin 67, and .68. is the pump piston. which is moved. by the a n 0 by means the eve 69. The Pump lever 69 is pivotally mountedon the frame at 71.. .t

In Fi'. .1 of the drawing, the back sition of the casting pot is shownin lines,.,and. the frontposition of {the same in dotted lines, As will be se afr m that figure, -the piston in the front ,position would be in a lower position in' the cylinder than 1n the back position,

Specification of Letters Patent Mergenthaler system, in which P mpso that Patented Nov. 28, 1911. Divided and this application filed September there would be the above mentioned disadvantages. In reality, the difference in the position of the pump piston is about 15 mm.

According tothis invent-ion, thepump cam 70 is modified in such mannerthat it has a gradient 80 located along that portion of'its track which corresponds in time to the forward movement of the casting-pot, the said gradient being so timed and proportioned that it acts upon the lever 69 so as to elevate the pump piston to. an extent suflicient t-ocounteract the relative movement between the piston and pot previously referred to. v In ot-her words, additional means are thus provided. to preserve the relative relation of the piston and pot, notwithstanding the oscillatory motion of the latter Moreover, an improvement has been made also in the pump cylinder itself. As is known the pump cylinder, is provided with an opening fordrawing in the liquid metal. In old I construct-ions the opening had to' be comparatively large asit= was made in the shape of acylindrical perforation'and consequently the metal could enter the cylinderv only with strong contraction, moreparticularly; as, the opening. in oneslimw e ranged n'a d of e-p mp Qy ind 17. at of t the metal ,the. latter was and comparativelycol d. d I According to-this invention (Figs- 2and 3), the above disadvantageis obviated ,by shifting the openin'g td a point at which o ng, me yato a. po ntrem e omthat wherethe solid metal is introduced, and by n k n'gt perf ra q ifa en l hape i e sntf fi rsfim -h known ments, generally speaking, only by the fact whi h; ow s o t e chargin not very liquid the; metal is. not exposed, to such astrong the cylin that the opening 72 through which metal is drawn into the cylinder, is movedaway from the point at which the metal is introduced, and is made of a conical shape and of considerably smaller size than in the'previous constructions. The pump piston 68 is normally in such a position that its lower edge is flush with the upper edge of the hole, so

, that it becomes operative almost at once.

The cylinder 73 itself can be made a little lower than before, so that there is less possibility that the .dirt and sediment settling on the to of the metal, would be drawninto der; this can be prevented in a still more eflicacious manner by providing the cylinder with a cover 74.

Having now particularly described and ascertained the nature of my invention and in what manner the same is to be performed, I declare that what I claim is:

1. In a line setting and type line casting machine in combination a casting pot containing a pump device, means for oscillating the casting pot to casting position, a pump plunger and means for controllin the movement of the plunger, the said p unger resting in its position relatively to the casting pot during the oscillation of the casting pot.

2. In a line setting and type line casting machine in combination a casting pot containing a pump device, means for oscillating the casting pot to casting position, a pump plunger-and means for controlling the movement of the plunger, the said pump plunger having an additional" movement simultaneously with the movement of the casting pot.

3. In a line setting and type line casting machine in combination a casting pot cons taining a pump device, means for oscillating the casting pot to casting position, a pump plunger and means for controlling the movemachine in combination a casting pot containing a pump device means for oscillating the casting pot to castin position, a pump plunger and a cam dis for driving the pump plunger said cam disk being provided at that part of the cam which corresponds to the forward movement of the casting pot with a gradient raising the pump plunger during the forward movement of the casting pot. L.

5. In a typographical machine comprising casting mechanism, the combination of a movable casting-pot and a suitably actuated pump, with means whereby the relative relation of the pot and. pump is preserved during the movement of the latter.

6. In a typographical machine comprising casting mechanism, the combination of a movable casting-pot, a pump, and a cam to control the action of the pump the said cam bein so formed as to control t e ump during 516 movement of the pot in or er to preserve their relative relation.

7. In a typographical machine comprising casting mechanism, the combination of the casting-pot and the pum cylinder located therein, the said cylinder being formed with an opening for the molten metal and having a gradually decreasing cross-section.

In witness whereof I have hereunder setmy hand'in presence of two witnesses.
